The vast majority of the universe is made up of dark energy, dark matter, and ordinary matter. Dark energy is the mysterious force that is accelerating the expansion of the universe. Dark matter is an invisible form of matter that does not interact with or absorb light, but it makes up about 27 percent of the universe’s mass and energy.
Ordinary matter is the type of matter we are familiar with and it consists of atoms and molecules. It makes up only 4. 5 percent of the universe’s mass and energy. Together, these three components make up 99.
9 percent of the universe.

What contains 99% of matter in the solar system?
The majority of matter present in the solar system is contained in the Sun. The Sun contains around 99% of all of the mass in the solar system, with the remaining 1% being made up of the other planets, asteroids, comets, meteors and other such material.
All of the planets, asteroids and comets together contain much less combined mass than the Sun, making it by far the largest mass in the solar system.
Where does about 99% of all matter contained in the solar system exist?
The vast majority of matter in the solar system, around 99%, is contained in the Sun. The remaining 1% is found elsewhere including the other planets, asteroids, comets, and interplanetary dust. The Sun is made up of primarily hydrogen and helium, as well as heavier elements like oxygen, carbon, and iron, which together make up all of the planets, moons, and other bodies that orbit the Sun.
The other planets and objects in the solar system are made up of a variety of different substances and materials, including ice and rock.
Is the universe 99.9% plasma?
No, the universe is not 99. 9% plasma. According to estimates from the Chandra X-ray Observatory and other instruments, the universe is about 73% dark energy, 23% dark matter, and only about 4% of the universe is made up of atoms, the form of matter we can see and interact with.
Of that 4%, only 0. 1% of the universe is in the form of plasma, which is a hot ionized gas composed of positively charged particles and negatively charged electrons. The majority of interstellar gas is actually neutral, not plasma.
Thus, while plasma is an important component of the universe, it does not comprise the majority or even close to the majority of the universe.
Why does about 99% of the total mass of the atmosphere live within a height of 32 km from the earth surface?
The majority of the Earth’s atmosphere lives within a height of 32 km (20 miles) from its surface because that is where the greatest concentrations of atmospheric particles can be found. The atmosphere is composed mainly of nitrogen, oxygen, and argon molecules, which are the most abundant in the lower layers.
The lower levels are also the densest, preventing the atmosphere from thinning out too much and thus allowing it to exert a strong influence on the Earth’s climate and weather. Additionally, the lower atmosphere is where most of the clouds form, due to the combination of atmospheric moisture and warm temperatures.
This is why the troposphere, which is the main layer of the atmosphere and the one where most of the weather takes place, extends only up to about 32 km (20 miles) from Earth’s surface. Beyond this distance, the atmosphere rapidly thins out and by the time you reach an altitude over 100 km you’ve already reached the edge of space.
Is the Sun 99% of the galaxy?
No, the Sun is not 99% of the galaxy. Our Sun is a star located in the Milky Way galaxy, which is an average-sized spiral galaxy with hundreds of billions of stars. In terms of mass, the Sun makes up about 0.
85% of the entire galaxy. This may seem like a lot, but the Milky Way is so massive that it is made up of more than just the Sun. A majority of the mass is comprised of dark matter, which makes up about 27% of the total galactic mass.
The remaining mass is in the form of gas, dust, and the stars themselves, with our Sun accounting for just 0. 85%.
Does plasma make up all stars?
No, not all stars are made up of plasma. Plasma is a type of matter, made up of electrically charged particles, that can conduct energy and exists in stars, interstellar gas, and other celestial objects.
However, there are different types of stars, with different compositions. For example, stars on the main sequence, the most common type, are typically composed of 75% hydrogen and 25% helium by both mass and volume.
This accounts for their luminosity and the production of solar radiation. These stars may also have metals and other elements present, but not in significant amounts. Other types of stars, such as white dwarfs, have many elements besides hydrogen and helium, and even carbon.
They are made up of a plasma of the various elements that is much denser than in main sequence stars. Therefore, not all stars are made up of plasma.
